Web24 de abr. de 2024 · If the bonds are ionic, the atoms can't be considered polar or non-polar. Examine each of the atomic elements contained within the molecule. Generally, bonds between two of the same atoms, such as nitrogen (N2) or oxygen (O2) have an even distribution of electrons, making the atoms non-polar. Webelectronegative atoms (e.g. N, O) in polar functional groups such as amines (-NH 2) and alcohols (-OH). Overall, polarity is a balance of the non-polar parts and polar parts of a molecule and it can be convenient to mentally break a molecule into its polar and non-polar components.
